i just received the master collection of the CS4 suite, and was installing it earlier. I put in each disc to install and walked away and let the computer do its thing. i came back and it never asked me to insert disc 4, is that normal? i came back after it installed disc 3 and it was just sitting at my desktop.

also, if i wanted to uninstall the CS4 suite, should I deactivate/delete the serial number from the machine before i do it, if I'm just going to reinstall it on the same machine right away? or do i not touch that stuff?
